摘要： The sensitized guinea pig was employed as a model to study the effect of immunological activation of resident mast cells on neuronal activity in the airways. The trachea was isolated with the vagus nerves and vagal sensory ganglia intact. Using conventional electrophysiological recording techniques, we noted that antigenic stimulation led to an increase in the sensitivity of sensory nerve endings located in the airway wall. Moreover, previous work has revealed that antigen challenge potentiates action-potential-driven tachykinin release from afferent fibers in the guinea pig isolated airway. Anatomical and electrophysiological studies indicate that tachykinin-containing sensory fibers directly innervate the local parasympathetic ganglion neurons in the airway. Therefore, antigen-induced increases in the excitability of sensory fibers in the airways can increase parasympathetic tone in the airway by increasing central and peripheral reflex arcs. In addition, we have found that antigen stimulation has direct effects on the excitability of the parasympathetic ganglion neurons. Considered together, the data demonstrate that increased vagal sensory and parasympathetic activity may be a consequence of the allergic reaction in the airways.

摘要： 现代神经生理学的研究结果表明:神经冲动从中构传出后,还要返回中枢,使中枢神经系统对活动的情境作出评价、判断和调节.著名的美国心理学家桑戴克也说:一个人对于他自己的活动,知道与不知道结果,效率是大不相同的.人的活动是由其活动的结果所调节的.根据以上原进,多年来,我利用学生的试卷,从“判改、讲评、总结”三方面入手,进行信息反馈.其结果显示效果尚可.本着抛砖引玉的目的,现介绍具体做法.

摘要： EXP is a Macintosh program for doing quantitative neurophysiology. It supports signal design, simultaneous signal output and data collection, spike sorting, histogram production, and many other analysis features. The hierarchical structure used to design protocols provides a straighforward method for designing complex experiments. The degree of automation supported by the program makes it possible to perform large-scale experiments and to collect and analyze large quantities of data in a reasonable amount of time. It has been used successfully in a large number of experimental paradigms by several different researchers. EXP is one of several cooperative programs designed to help perform neurophysiological experiments. These programs can be used in tandem not only to collect and analyze data but to help interpret and present results as well. The programs contain mechanisms to encourage re-analysis or 'virtual experiments' on data collected previously by oneself or other researchers.
